In this thesis I examined two important aspects of clearcut harvesting along small headwater streams and their riparian zones. The objectives of the study were: 1) to investigate the impacts of clearcut harvesting on the ...

In boreal forest ecosystems, stand age is a key driver of forest ecosystem productivity, carbon storage/sequestration, and other ecosystem functions. The age-related decline of aboveground productivity is well known in ...

Mercury is a contaminant of global concern as it is present in all biota and ecosystems around the world. Small streams are influenced by the terrestrial systems that feed them. I examined the presence of mercury in small ...

In chapter 1 of this study the relationship between spatial, chemical, and
biological factors and their influence on mercury concentration s in walleye were

Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ...

Emulation of natural disturbance processes and their effects is important to maintain the structure and composition of managed forests. In boreal mixed forests, clearcutting has been considered as management practice ...
